Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, and in particular to a reusable and easy-to-fold cardboard box. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and there are various specifications and models. Cardboard boxes commonly use three-layer and five-layer boxes, while seven-layer boxes are less common. The color and feel of different types of paper are different, and the paper produced by different manufacturers is also different in color and feel.

[0003] Most existing cardboard boxes are used for express delivery packaging. After opening the package, users will fold the cardboard boxes for storage or discard them directly. Discarding them after use causes a great waste of resources. Folded cardboard boxes take up a lot of space and often have the cardboard bent and collapsed, making it impossible for the cardboard boxes to be supported and reusable.

[0004] Therefore, we propose a reusable and easy-to-fold cardboard box. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a reusable and easy-to-fold cardboard box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reusable, foldable cardboard box includes a box body. A first support rod is fixedly installed on each of the two corresponding sides of the bottom of the box body. A second support rod and a third support rod are rotatably installed between the two first support rods. A rotating rod is rotatably installed between the second and third support rods. A first support vertical rod is fixedly installed on each of the two first support rods on corresponding sides. A second support vertical rod is fixedly installed on one side of each of the second and third support rods. The first and second support vertical rods are interlocked.

[0008] As a further embodiment of this utility model: the first support base rod, the second support base rod, and the third support base rod are all rotatably connected by a bottom rotating shaft, and a support plate is fixedly installed between the two first support vertical rods.

[0009] As a further embodiment of this utility model: both the second and third support base rods are rotatably mounted with support rods between them and the rotating rod; the upper surfaces of the first, second, and rotating rods are all provided with limit slots; and the lower surfaces of the first, second, and rotating rods are all fixedly mounted with limit buckles.

[0010] As a further embodiment of this utility model: a first connecting rotating shaft is rotatably mounted on one side surface of the second supporting vertical rod, the first connecting rotating shaft is rotatably connected to a connecting block, and the end of the connecting block away from the first connecting rotating shaft is rotatably connected to a second connecting rotating shaft.

[0011] As a further embodiment of this utility model: a connecting rod is rotatably mounted on one end of the second connecting rotating shaft away from the connecting block, and an auxiliary block is fixedly mounted on one side surface of the connecting rod.

[0012] As a further embodiment of this utility model: springs are fixedly installed on the corresponding two sides of the auxiliary block, and a locking block is fixedly installed on the end of the spring away from the auxiliary block.

[0013] As a further embodiment of this utility model: a hole is provided on one side surface of the first support vertical rod, and limit holes are provided on the corresponding two sides surface of the first support vertical rod, and the hole is connected to the limit hole.

[0014] Compared with the prior art, this utility model provides a reusable and easy-to-fold cardboard box, which has the following advantages:

[0015] 1. This utility model features folding lines on corresponding sides of the carton body, located at the rotating rod. Users can disassemble the locking structure between the first and second support rods, preventing them from connecting. The second and third support rods are rotatably mounted between the two first support rods. By pressing the folding lines, the second support rods on the second and third support rods come into contact, simultaneously engaging the two first support rods. This allows the carton body to fold, resulting in a smaller footprint for easier storage. When needed again, the internal support device can be opened.

[0016] 2. This utility model, by simultaneously setting a support plate and a support rod, can more stably support the carton body and prevent the carton body from being crushed. At the same time, limit slots are opened on the upper surface of the first support vertical rod, the second support vertical rod, and the rotating rod, and limit buckles are fixedly installed on the lower surface of the first support vertical rod, the second support vertical rod, and the rotating rod. The user will lock the limit buckles into the limit slots, thereby extending the first support vertical rod, the second support vertical rod, and the rotating rod, so that the support device can be used for carton bodies of different heights.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: A reusable, easily foldable cardboard box, such as... Figures 1-3As shown, the device includes a carton body 1. A first support rod 2 is fixedly installed on the corresponding sides of the bottom of the carton body 1. A second support rod 3 and a third support rod 301 are rotatably installed between the two first support rods 2. A rotating rod 4 is rotatably installed between the second support rod 3 and the third support rod 301. A first support vertical rod 8 is fixedly installed on the corresponding sides of the first support rod 2. A second support vertical rod 9 is fixedly installed on one side of both the second support rod 3 and the third support rod 301. The first support vertical rod 8 and the second support vertical rod 9 are interlocked. The carton body 1 is configured with fold lines on corresponding sides, located at the rotating rod 4. This allows the user to... The locking structure between the first support vertical rod 8 and the second support vertical rod 9 is disassembled, so that the first support vertical rod 8 and the second support vertical rod 9 are not connected. The second support bottom rod 3 and the third support bottom rod 301 are rotatably installed between the two first support bottom rods 2. The worker squeezes the folding line, so that the second support vertical rods 9 on the second support bottom rods 3 and the third support bottom rods 301 come into contact. At the same time, the two first support bottom rods 2 come into contact, so that the carton body 1 can be folded. The folded carton body 1 occupies less space and can be better stored. When it is needed for reuse, the support device inside the carton body 1 can be opened.

[0027] like Figures 1-3As shown, bottom rotating shafts 5 are rotatably connected between the first support base rod 2, the second support base rod 3, and the third support base rod 301. Support plates 6 are fixedly installed between the two first support vertical rods 8. Support rods 7 are rotatably installed between the second support base rod 3 and the third support base rod 301 and the rotating rod 4. Limiting slots 10 are provided on the upper surfaces of the first support vertical rod 8, the second support vertical rod 9, and the rotating rod 4. Limiting buckles 11 are fixedly installed on the lower surfaces of the first support vertical rod 8, the second support vertical rod 9, and the rotating rod 4. Because bottom rotating shafts 5 are rotatably connected between the first support base rod 2, the second support base rod 3, and the third support base rod 301, and the first support base rod 2 is fixedly connected to the bottom rotating shaft 5, the second support base rod 3 and the third support base rod 301 rotate when the carton body 1 is folded or unfolded, thereby allowing the first support base rod 2 to rotate when the carton body 1 is folded or unfolded. When the second support rod 3 and the second support vertical rod 9 on the third support rod 301 come into contact, the carton body 1 can be folded. When the second support vertical rod 9 on the second support rod 3 and the third support rod 301 separate and come into contact with the first support vertical rod 8, the carton body 1 can be supported for reuse. At the same time, the support plate 6 and the support rod 7 can more stably support the carton body 1 and prevent the carton body 1 from being crushed. In addition, the first support vertical rod 8, the second support vertical rod 9 and the rotating rod 4 are all provided with limit slots 10, and the first support vertical rod 8, the second support vertical rod 9 and the rotating rod 4 are all fixedly installed with limit buckles 11. The user will lock the limit buckles 11 into the limit slots 10, thereby extending the first support vertical rod 8, the second support vertical rod 9 and the rotating rod 4, so that the support device can be used for carton bodies 1 of different heights.

[0028] Example 2: A reusable, easily foldable cardboard box, such as... Figures 1-5As shown, a first connecting shaft 12 is rotatably mounted on one side of the second supporting vertical rod 9. A connecting block 13 is rotatably connected to the first connecting shaft 12. A second connecting shaft 14 is rotatably connected to the end of the connecting block 13 away from the first connecting shaft 12. A connecting rod 15 is rotatably mounted on the end of the second connecting shaft 14 away from the connecting block 13. An auxiliary block 18 is fixedly mounted on one side of the connecting rod 15. By setting the auxiliary block 18, and providing corresponding limit structures on both sides of the auxiliary block 18, when the carton body 1 needs to be folded, the user squeezes the limit structures to disengage the auxiliary block 18 from the first connecting shaft 12. The supporting vertical rod 8 is rotatably connected to the connecting block 13 via the connecting rod 15 and the second connecting rotating shaft 14. The connecting block 13 is a right trapezoid. At the same time, the connecting block 13 is rotatably connected to the second supporting vertical rod 9 via the first connecting rotating shaft 12. When the auxiliary block 18 disengages from the first supporting vertical rod 8, it drives the connecting rod 15 to move horizontally, thereby causing the connecting block 13 to rotate. This causes both the auxiliary block 18 and the connecting rod 15 to disengage from the first supporting vertical rod 8, thus decoupling the first supporting vertical rod 8 from the second supporting vertical rod 9, making it easier for the user to fold the carton body 1.

[0029] like Figures 1-5 As shown, springs 19 are fixedly installed on corresponding sides of the auxiliary block 18. A locking block 20 is fixedly installed on the end of the spring 19 away from the auxiliary block 18. A hole 17 is opened on one side surface of the first support vertical rod 8. Limiting holes 16 are opened on corresponding sides of the first support vertical rod 8. The hole 17 communicates with the limiting holes 16. By setting the auxiliary block 18 to be fixedly installed on corresponding sides of the springs 19, and the locking block 20 is fixedly installed on the end of the spring 19 away from the auxiliary block 18, when the first support vertical rod 8 is connected to the second support vertical rod 9, the user squeezes the locking block 20 so that the locking block 20 and the auxiliary block 18 and connecting rod 15 are connected to the first support vertical rod 8 through hole 17. When the locking block 20 reaches the hole 17, the spring force of spring 19 causes the locking block 20 to pop out and lock in the limiting hole 16. Thus, the first support vertical rod 8 and the second support vertical rod 9 are stably connected. When the first support vertical rod 8 and the second support vertical rod 9 are separated, the user squeezes the locking block 20 and pulls the connecting rod 15 in the opposite direction of hole 17, so that the locking block 20, auxiliary block 18 and connecting rod 15 are all disengaged from the first support vertical rod 8, and then the staff can fold the carton body 1.

[0030] Working principle: When the carton body 1 needs to be folded, the user squeezes the locking block 20 and pulls the connecting rod 15 in the opposite direction to the hole 17, causing the locking block 20, auxiliary block 18, and connecting rod 15 to disengage from the first support vertical rod 8. At the same time, the user squeezes the folding line, causing the second support bottom rod 3 and the second support vertical rod 9 on the third support bottom rod 301 to come into contact. Simultaneously, the two first support bottom rods 2 come into contact, thus folding the carton body 1. When the carton body 1 needs to be used again, the user pulls the contacting second support vertical rod 9, causing the second support... When the second support rod 9 on the support rod 3 and the third support rod 301 separates and contacts the first support rod 8, the carton body 1 can be supported. At the same time, the user squeezes the locking block 20, so that the locking block 20, the auxiliary block 18 and the connecting rod 15 are connected to the first support rod 8 through the hole 17. When the locking block 20 reaches the hole 17, the elastic force of the spring 19 causes the locking block 20 to pop out and lock in the limiting hole 16. Thus, the first support rod 8 and the second support rod 9 are stably connected, and the carton body 1 can be supported for reuse.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
